I'd argue that you can define a function within a function, but that interning a var within a function is a smell, and doing it with a constant, rather than argument-supplied or computed, name, in a function or in a macro, is a stench (e.g. (defn foo [x y z] (defn bar ... ))) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
